Special Conditions; Piper Aircraft, Inc., Piper PA-32R-301T, Saratoga II TC, and PA-32-301FT, Piper 6X; Protection of Electronic Flight Instrument Systems (EFIS) for High Intensity Radiated Fields (HIRF)

These special conditions are issued to Piper Aircraft, Inc., 2926 Piper Drive, Vero Beach, Florida 32960, for a type design change for the Piper PA-32R-301T, Saratoga II TC, and PA-32-301FT, Piper 6X. These airplanes will have novel and unusual design features when compared to the state of technology envisaged in the applicable airworthiness standards. These novel and unusual design features include the installation of electronic flight instrument system (EFIS) displays, Model G-1000, manufactured by Garmin AT, Inc., for which the applicable regulations do not contain adequate or appropriate airworthiness standards for the protection of these systems from the effects of high intensity radiated fields (HIRF). These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to the airworthiness standards applicable to these airplanes.
